Answer 2

Glucose + Oxygen—> Carbon Dioxide + Water + Energy

Question 3

Word Equation For Anerobic Respiration in MUSCLES

Answer 3

Glucose—-> Lactic Acid + Energy

Question 4

Difference between Aerobic and Anerobic

Answer 4

Anerobic doesn’t use oxygen
Aerobic Does

Question 5

Answer 5

Anerobic

Question 6

Which Respiration Releases More Energy?

Answer 6

Aerobic

Question 7

What does Anerobic Respiration Produce in Yeast

Answer 7

Alcohol/Ethanol

Question 8

Word Equation for Anerobic Respiration in Yeast

Answer 8

Glucose—> Carbon Dioxide + Ethanol + energy

Question 9

Method of Experiment of Anerobic Respiration in Yeast

Answer 9

1) Boil a solution of Alcohol
2) Cool the glucose before adding yeast cells
3) Add a layer of oil to glucose containing yeast

Question 10

Why is Glucose Boiled

Answer 10

To remove oxygen
Kill Bacteria

Question 11

Why is glucose cooled before adding yeast cells

Answer 11

It can kill the yeast cells if it is too hot

Question 12

Why is a layer of Oil Added?

Answer 12

So it doesn’t react with oxygen

Question 13

Changes Observed from the Anerobic respiration in Yeast Practical

Answer 13

Limewater turns milky
bubbles
heat produces

Question 14

Where is the Respiratory System in Human

Answer 14

Chest

Question 15

What is the chest surrounded by?

Answer 15

Intercostal Muscle

Question 16

What is below intercostal muscle

Answer 16

Diaphragm

Question 17

What happens to the air as it passes through the nasal cavity?

Answer 17

1) It is Warmed
2) It is Filtered

Question 18

How are lungs adapted?

Answer 18

1)Large Surface Area
2)Thin
3) Moist
4)permeable
5) A good blood supply
6) A good Diffusion Gradient

Question 19

Explain why the lungs have large surface area?

Answer 19

Each lung has many small air sacs called alveoli, which provide a large surface area for gas exchange, helping humans breathe efficiently.

Question 20

Explain the Lung’s Permeable Surfaces

Answer 20

Oxygen and Carbon Dioxide can pass through the walls of Alveolus easily

Question 21

Explain the Lung’s good diffusion gradient

Answer 21

Maintained by blood supply and constant breathing in and out

Question 22

Explain the Lungs Good Blood Supply

Answer 22

Capillaries around alveoli help oxygen get into the bloodstream and take carbon dioxide back to the lungs for breathing out, keeping our body supplied with oxygen and removing waste gas.

Question 23

Explain the Lung’s Moisture

Answer 23

Oxygen dissolves in the liquid before diffusing across the wall of alveolus . this helps increase the rate of diffusion

Question 24

Define Breathing Rate

Answer 24

is the number of breaths per minute

Question 25

Define Recovery Rate

Answer 25

is the time taken for your breathing rate to normal

Question 26

Is there a link between the levels of fitness and breathing rate

Answer 26

The Fitter you are the less you need to breath as your lungs take in more air when inhaling

Question 27

Is there a link between levels of fitness and recovery time?

Answer 27

The fitter person has a shorter recovery time
The fit persons heart pumps more blood in one pump, so it is faster to return to normal

Question 28

If a student becomes fitter over time how would this affect his/her recover time?

Answer 28

The recovery time would become shorter

Question 29

Explain Respiration During Exercise

Answer 29

Exercise increases muscle contraction and energy demand.
Cells carry out more respiration, requiring more oxygen and producing more carbon dioxide.
Muscles extract more oxygen from the blood and release more carbon dioxide into it.
Breathing becomes deeper and faster to replenish oxygen and remove carbon dioxide, enhancing gas exchange in the lungs.

Question 30

Define Respiration

Answer 30

The release of energy from food
